Well, I have tested my Xeon 3110 on Asus P5Q-E
There are no any probs with it. With 570x6 you can work in BIOS already, 540x6 it can load OS and work in apps.
Optimal and stable result is near 500x8.5.
But DFI pass only 500x6 and hangs at 510x6. Same FSB wall on motherboard I saw at other people, and even in some reviews.
It seems that many x35 chipsets, especially first revisions, just couldn't go over 500

Those people in DFI was too fast at this time with x35, before they made new models with some time lag.
Time to move to i7?
